I am looking for a truck and have noticed more than one used PS Ford w/ moderate miles, (125-150k), and (1) dead cylinder. (For a "fixer" price, obviously). I know that these motors have a really good rep in general, (don't they?), so I am wondering if they burn valves? I cannot imagine how the rings in one hole would fail on more than one motor, but then they are turbo-ed w/ an effective CR of probably ~22:1 or something.
There is quite a difference in cost between repairing one head and a new longblock, and since it's on ebay I cannot really dig deep in it. I would bid based on it needing a motor, (which all others are doing I'm pretty sure), what are the odds of just a burned valve? Anyone know? TIA.
